QUACK-GRASSI-DESTROYING MACHINE.

Specification of Letters Patent;

Application filed September 20, 1910. Serial 110. 582,905.

l'ocll whom it may-concern: I Be it known that I, JOHN S. JOHNSON, a

citizen of the United States, residing at Vaukon, in the county of Allamakee and State of Iowa, have invented certain new and useful Improvements in Quack-Grass- Destroying Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertain's to make and use 'the'same.

This invention relates to certain new and useful improvements in quack grass destroying machines, the object being to provide a machine which is so constructed that the grass will be removed by a plow and carried through a perforated casing by an I elevator where the soil will be removed I ,to provide a machine which is exceedingly simple and cheap in construction and one which is so constructed that the plow can be readily raised 'or lowered in order to remove a thick or a thin sod in order to meet difthe same, and it will be seen that the same is supported in such a position that the fuel ferent requirements.

Another object of my invention is to provide novel means for driving the elevator within the sifting casing, whereby the sod removed by the plow will be broken up and the soil removed therefrom in traveling through the same.

In the drawing, I have shown/a side elevation of my improved machine partly in section, in which- 1 indicates a wheeled frame supported-by rear wheels 2 and front wheels 3, the rear wheels 2 being mounted: on an axle 4, on which is pivotally mounted asifting casing 5 which is provided with a perforated bottom 6 and in which is mounted an endless ward end ,of'th'e casing carries a plow 10 which is provided with a suitable standard 11 mounted in suitable bearings formed in the frame .1 so as to hold the same firmly and relieve the strain from the casing. Connected to the casing is a link 12 which is connected to the arm of the crank lever 13 mounted on the frame which is provided with a latch- 14: (to-acting with'a segmental rack 15 secured on the frame in such a manner that tl1e plow and easing can be adjusted vertically and locked in their adjusted positions.

Extending downwardly from the rear end of the casing 5 is a reticulated conical casing 16 adapted to receive the grass from the casing 5. .Arranged within this casing-are a plurality of oil burners 17 for (lburning.

ed on a suitable support 19 arranged 'upon the casing 5, as clearly shown, and said tank may be provided with a pump which is driven by a suitable belt ,and pulley 0perated by the axle of the frame. Extending from the tank 18- are pipes 19' carrying burners 20 which extend.into the casing 5,

so that grass'will be partly burned within thecasing 5 before it reaches the casin '16. The tank is provided with a suitable filing cap which can be removed in order to fill will be fed to the burners by gravity.

From the foregoing description, it will be seen that as the frame is drawn along, the plow will remove the sod and deposit the same into the casing 5, through which it is carried by the endless elevator 7 -which breaks the same up and removes the dirt therefrom, which drops through the perforated bottom back on to the surface over which the machine is traveling. The'grass is discharged-from the upper end of the casing'5 into the reticulated casing 16 in which'it is destroyed by the burners 17, and

is then discharged therefrom backon toi the ground which will enrich the ground as well asdestroythe grass.

The burners 17 are adapted to project strong blastflames toward the outlet of the charge of the products of combustion will be greatly facilitated. The air currents that are created in the casing 16 serve to distribute products of combustion, particularly the ash of the grass, over a wide area of ground,

' S0 that they can be readily incorporated in the ground surface.

' What I claim is 1. A grass destroying machine, comprising a wheeled frame having aplow, a casingprovided with an endless elevator adapted to receive the sod from the plow, and a reticulated casing arranged at the upper end of said casing provlded with burners.

2. A grass destroying machine, compris- A machine for destroying grass, com-.

prising a wheeled frame, a casing pivotally supportedby the rear axle of the-frame, a

plow carried by the forward end of said frame, a lever for actuating said casing and plow, an endless elevator-mounted in said casing, a sprocket wheel carried by the axle carrying a chain for driving said endless elevator, and a reticulated discharge casing arranged at the upper end of said casing having burners.

4. A machine for destroying grass, comprising a'wheeled frame, a casing pivotally supported by said frame having a perforated bottom, a plow carried by the forward end of said casing, means for raising and lowering said plow and easing, an endless elevator mounted in said casing, means for operating said endless elevator, a reticulated conical discharge casing extending clownwardly fromthe rear of said casing, and burners extending into said discharge casing.

5. In a grass destroyer, a frame, grass removing and elevating means carried thereby, a reticulated casing-carried by said 1-neans and provided with an outlet and a burner projecting into the casing.

(3. In a grass destroyer, a frame, grass removing and elevating means carried thereby, a reticulated casing having a discharge end and carried by said elevating means and arranged to receive grass therefrom, and a burner projecting into the casing and toward the discharge end thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN S. JOHNSON.
